Toallwlwmitmay concern:

Be it known that I, Cani. A. Snswsox, citizen of the United States, andresident of the borough of Manhattan, city of New York in the countyofNew York and State of New York, have invented certain new and usefulImprovements in Calculating Machines, of which the following is aspecification.

My invention relates to calculating chines and more particularly tospiral removing mechanism for such machines.l

In calculating machines, in which carrying mechanism of certain kinds isemployed to carry from a wheel of lower order to the next wheel ofa`higher order throughout the series, there is a likelihood ofdeveloping what is known as spirals during the carrying and clearingoperations. That is to say the numerals on the re 'ster wheels, exposedat the sight-openings in the totalizer frame, instead of appearing in astraight horizontal line will appear in a spirally disposed arrangementwhich sometimes results in the im roper actuation of the register andgives a alse reading on the register wheels, as is well understood inthe art. v

The main object of my invention is to provide simple and highly elicientrectifying mechanism for overcoming t h`is difficulty and forautomatically aligning the wheels after each operation thereof to removeany spiral that may develop.

A further object of my invention is to provide simple and eicientmechanism ofthe character specified which maybe readily incorporated inexisting computing machines vwithout modifying, or materially.modifying, the structural features of such machines as they now exist.

To the above and other ends which will hereinafter appear, my inventionconsists in the features o-f construction, arrangements of parts, andcombinations of-y devices set forth in the following specification andparticularly pointed out in the appended claims.

In the accompanying drawings, wherein like reference characters indicatecorresponding parts in the different views,

I have shown my invention in the present instance embodied in aRemington accounting machine of the character disclosed, for example, inthe patent to John C. Wahl, No. 1,270,471, dated June 25, 1918, in whichthe devices of the present invention may be readily embodied withoutmodifying, or materially modifying, structural features of said machineas they now exist. YIt should be understood, however, that the inventionis not restricted to embodiment in such machines but may be employedwherever found available in various styles of computing machines.

lThe Remington accountingmachine is a combined typewriting and computingmachine in whlch one or more vertical totalizers are carried by a truckconnected to the carriage of the ty` writing machine to traveltherewith. ach vertical totalizer carries registering mechanismcontrolled by actuating mechanism carried by the frame of the machineand o i ated b the numeral keys of the t pewriting mac4 ine. When atotalize has geen brought to the computin zone an actuation of a numeralkey wil register in said totalizer a number according -to the value ofthe key which has been actuated, either for addition or subtraction, inaccordance with the setting of the machine. The truck advancing one stepat each operation of a numeral key. brings wheels of the totalizersuccessively into en agement with the master wheel or device o theactuating mechanism for actuation thereby. When used for addition, forexample, each register wheel in making a complete revolution and inmoving from the 9 position to the 0 positionv will result in the carring mechanism turning the register wheel o the next higher order onespace adding one thereto, this movement at times being transmittedthroughout the series from a wheel of the lowest order to a wheel of thehighest order.

In the accompanying drawings I have shown only so much of the Remingtonaccounting machine as is necessary to arrive at an understanding of myinvention in its inclusion therein, the mechanism 'of this machine beingwell understood in the art and fully disclosed in the said Wahl patent.

A portion of the truck, by which one or nioie vertical totalizeis arecarried, is indicated by the reference numeral 1 in Fig. 1. Eachtotalizei comprises a frame Q.' detachably connected to and adjustableto different positions along the truck 1. Each totalizer frame 2, asordinarily constructed, carries a series of dial wheels 3, each providedwith a gear wheel 3a; a series of meshing idle wheels 4; a series ofgears 5 each having thirty teeth which mesh with the gears et; and aseries of locking wheels 6. Each gear 5 has fixed on the left-hand side'thereof a wheel a formed with three carrying teeth Z) spaced apart atintervals of ten teeth of the coiiipanion gear 5. Each gear 5 also hasfixed thereto a wheel 7 arranged to the left of the wheel a and havingits periphery formed with three notches 8 arranged at intervalscorresponding to the positions of the carrying teeth Zi. Each wheel 7constitutes a member of a Geneva gear which coacts with the companiongear, star or locking wheel 6. Each wheel 6 carries a gear 9 on therighthand side thereof with which the carrying teeth Zi coact, and alsohas on the left-hand side thereof a gear (not shown) which meshes withthe wheel 5 of the next higher order. When the teeth of a wheel 6 engagethe periphery of the companion wheel 7 said wheel 6 is prevented fromturning. lVheii, however. a recess 8 is brought opposite a tooth of thecompanion wheel 6 as shown in Fig. 1, a carrying tooth engages theassociated gear 9 and turns said wheel 6 one unit; a tooth of the wheel6 passing through the registering recess 8 at this time. This turningmovement of the wheel 6 is transmitted through the gear on the left-handside thereof to the engaged gear 5 of the next highei` order and suchmotion in turn is transmitted to its dial wheel. In this manner motionmay be transmitted throughout the series from the lowest to the highestorder wheels to carry successively through all of the register wheels.

The truck 1 moving with the typewriter carriage brings the totalizer tothe computing Zone and the wheels 5 are brought successivelyv by a. stepby step movement in to mesh with a master wheel or device 10 w to beoperated successively thereby at succesmaster wheel 10 is carried by anactuator frame secured to the frame of the typewriting machine. Variousparts of the actuating mechanism by which the master wheel is controlledare carried by this frame, certain only of such parts being illustrated.This actuating mechanism comprises a series of links 12 each connectedat its lower end to the respective key lever of the numeral key for saidlink. The upper end of each link is pivoted to the associate socalledfan 13 that includes part of the full stroke mechanism and means bywhich motion is transmitted to various parts of the actuating mechanism.A cam 14 on each fan 13 coacts with a universal bar 15 carried by andadapted to turn in bearings in parallel arms 16 fixed t0 a rock shaft17. Also fixed to the shaft 17 is aA crank arm 18 to which a link 19 ispivoted at 20. The upper end of the link 19 is .slotted at 21 to receivea headed pin 22 carried by a master cam 23. This cam is xed on a shaft24: and is operative on a certain master dog (not shown) and on otherdevices, which for the purpose of my present invention need not beconsidered further than to point out that the parts in question operatein the usual manner, except that a certain aligning dog usually employedin the Remington machine and co-operative with the wheels 5. is omitted.An additional crank arm Q5 fixed on the rock shaft 17 carries alaterally projecting pin or roller QG co-operative with a cam 27. Thiscam is formed in a member 28 pivoted at 29 and carrying a so-calledlocking dog 30 which normally engages the master wheel 10 and serves todefinitely align the master wheel and hold it in position during thetime said wheel is not being rotated by the depression of a key.

illy improved aligning mechanism includes a crank arm 31 fixed on rockshaft 21 and carrying a laterally projecting pin 32 that projects intoan opening 33 in a carrier 3l pivoted on a. headed pin 35 secured to aframe plate 3G of the actuator. As the shaft 2t receives a clockwisemovement from its normal position as the arts are viewed in Fig. 1, thepin 32 wil be forced against the wall 33 of the opening in the carrier34:. turning the latter from the Fig. 1 to the Fig. 2 position. Theforward end of the carriei' 34 carries laterally projecting lugs 37between which is received a depending arm 38 at the right-hand end of analigning` bar or plate 39. A pivot pin 40 extends through the lugs 37and the arm 38 transversely of the bar 39 lto pivotally connect thealigning bar at one end to its carrier 3%. The lower end of the arm 33is formed with an enlargement 41 provided with an opening through whicha. pin 42 extends. This pin is secured at its inner end to and projectslaterally from the carrier 34. The diameter of the pin is smaller thanthat of the opening in the arm 38 through which the pin extends so asnot tointe'rfere with the pivotal movements of the aligning bar on itscarrier 34. A coiled expansion spring 43 surrounds the pin 42 and bearsat its inner end against the enlargement 41, and at its outer endagainst a stop or head 44 carried by the pin at the outer end thereof. Iprefer to detachably connect 4this head to the pin as best shown in Fig.From this view it will be seen that the pin 42 is provided with tworecesses, slots or cutouts 45 on opposite sides thereof and near itsouter end. This leaves an interniediate web 46 .between the slots, andleaves a head 47 at the end. The detachable head 44 is in the nature ofa washer of a thickness ycorresponding substantially to the width of theslots 45 and formed with a laterally extending slot '48 corresponding`substantially to the thickness ot the web 46 and with a. centraldepression 49` corresponding substantially to the shape and dimensionsof the head 47. It will be understood that when the spring 43 ismaintained contracted on the pin 42, the head 44 may be slippedlaterally on the pin through the openings 45 therein until the head iscentered on the pin. It' the spring is then released it will force thehead 44 to the right and seat the head 4T in the recess 49, thuslockingthe head 44 against accidental detachment, and holding it in thisposition so long as the force of the spring 43 is exerted thereon, butenabling the head to be readily detached when desired.

It Will be understood from what has been said the force of the Spring 43is exerted to hold the arm 38 against the carrier 34, or to return it tosuch position if moved therefrom. The spring therefore tends to hold thealigning bar 39 in the normal position, shown in Fig. 3, relatively tothe carrier 34, so that the two may swing together as one part aroundthe axis of the pivot 35, which is parallel with the aligning bar andwith the axis of the wheel 5. The left-hand end of the aligning bar 39is provided with a locking finger or lug 50 co-operative with thelocking or holding device that is automatically thrown into and out ofengagement therewith, as will hereinafter appear. I prefer to guide thisfinger 50, in its movement with the plate 39 and the carrier 34, in aguide slot 51 ot a bifurcated guide member 52 secured at to the plate,54 of the actuator frame. In order to further aid in guiding the carrier34, and to provide means for limiting its pivotal movements from andback to -normal position, I prefer to employ a headed pin the stem ofwhich extends through a slot. 56 in the carrier, as shown in Fig. 2.This pin is secured to the frane plate 36 and the head of the pinoverlapping the right-hand or outer face of the carrier guides'thelatter at its foward end between said head and the frame plate 36.

From an inspection of Fig. 4l it Will be seen that the upper engagingedge 39A of the aligning bar is of angular shape in cross section to litsnugly between the teeth of the wheels 5. Then therefore the bar isforced into place between said teeth the wheels engaged by the bar 'willbe properly aligned, It is not necessary to have the aligning bar coactwith the right-hand or lowe'st order wheel inasmuch as said wheel isproperl aligned by engagement with the master wieel, which is itselfaligned and held in proper position by the locking dog 30.

The carrier 34 is turned on its pivot 35 from the Fig. 2 to the Fig. 1or effective position, by a contractile spring 5T stronger than thespring 43 and connected at one end to a pin 58 which projects from theframe plate 3G, and connected at its other end to a pin 59 whichprojects laterally from the carrier. The movement of the aligning' bar39 with its carrier to the releasing position is effected by the cammingaction of the pin 32 against the carrier and against-the torce of thespring 5i'.

As thus tar described the construction is such that the tirst part otthe depression of a key is effective to swing the universal bar l5`before any motion is transmitted to the master wheel in a manner to bepresently described. This movement ot the universal bar results inmoving the parts controlled thereby from the Fig. 1 to the Fig. 2position, thereby withdrawing the locking dog 30 from the master wheel10 and withdrawing 1the 'locking bar 39 from engagement with thewheels'rthat coact therewith. In this movement, the bar,39 swings bodilywith its carrier 34 around the pivot and simultaneously disengages allthe wheels with which it coacts. The parts are held in this position bythe universal bar bearing on adwell 14a ot the cam 14 ot the actuatedfan 13 during part ot' the remainder of the. down stroke of the key, anduntil the universal bar clears the dwell 14"l and is freed from controlot the depressed key for independent return movement.

Itis not until after the above described preliminary operations ofreleasing the master wheel and the wheels 5, etc., have taken place thatthe master wheel is tui-ned the requisite distance during, say, the lasthalf oli/a. depression of a key to set up a number in the register. Theoperation of the inaster wheel is ett'ected by a series of goosenecks6() each formed as a part of a carrier 6l mounted to turn on thesupporting rod 62 on which the t'ans 13 also are mounted to turn. Eachcarrier 6l is associated with ins lll

' wheels and o rated by a fan 18 through an interm iste lost motionconnection omprising a pin 68 projecting laterally f1 `om the carrierinto s slot 64 in the companion fan 13. This lost motion connectionenables the above `described preliminary o ration to be effected beforethe upper wa 64'* of the slot in the o rated fan reaches the pin 63 andtakes uptic carrier of the goose-neck to cause an operation of themaster Wheel. It will be understood that cams 65 on the differentgoose-necks are so shaped that each gives a different extent of throwdepending on the value of the key to which the gooseneck is operativelyconnected. Each cam terminates in a slot 65a which acts as a dwell stthe high point of the cam. These goose-necks operate on pins or rollers66 carried by arms 67, only live of which are shown in the resentinstance. These arms project from t ie differential shaft 68 of themachine end radiate from said shaft to bring the pins 66 thereon intocri-operative relation with the cem 65. The usual means (not shown) areprovided for transmitting to the master Wheel the different extents ofmovement given to the differential shaft 68.

Thus fer l heve described in detail only the disengaging movement of thealigning plate or bar 39 from the wheels 5, it being understood that theengagement of the plate with seid Wheels and the aligning thereof doesnot taire place until after the master Whe-el has been actuated. nengaging the and aligning them, and thereby aligning the dial Wheels itis highly desirable cause the aligning bar 39 to engage the Wheelssuccessively' beginning at the right. ln order to effect this result lprovide the following means co-operative with those hereinbeforedescribed.

Referring especially to Fig. 3, it will be seen that the diderentialshaft G8 carries a crank arm 60 provided with a laterally projecting pin70. This pin is received 1n a cam slot 7l of a locking member 72 mountedon e heeded pivot pin 7 3 secured to the frame plate 54. The upper wall.of the cam slot continues as a surface 74 which when the member 72 is inthe actuated position is concentric to the center of the shaft 68. Thissurface 74 acts as a dwell to hold the locking member in its actuated orlocked position until the pin 7() re-enters the cam slot 7l andwithdraws ,the locking inember to releasing position, shownhin Fig. 3.The preliminary operations hereinbefore described et the first part of akey depression .l moves the aligning bar down to simultaneouslvdisengege the wheels 5, and leaves the locking linger in the lower endof the slot 5l. During a further depression of the key the differentialshaft 68 will be rocked by tlie'nctnsted goose-neck s distance deonthevvalue of the particular key depressed. The first part of thismovement of the differential shaft is efectivo to turn the lockingmember 72 in an anti-clockwise direction, as the parts are viewed inFig. 3. This brings the upper hook-like engaging portion 75 over thefinger 50 and prevents an upward or return movement of that end of thealigning bar. The construction and arrangement 0f the parts of theRemington accounting machine are such that near the termination of thedown stroke of a key the universal bar 15 drops olf the dwell 14 of theactuated fan 13, allowing the universal bar and the parts controlledthereby to return to their normal positions. Un the other hand, theactuated se-neck, the differential shaft 68 and-t e parts controlledthereby do not return t0 normal position until about the termination ofthe 11p-stroke of the key. By controlling the carrier 34 of the aligningbar 39 from the universal bar, and controlling the lockin member 72 fromthe differential shaft 68, am enabled to move the aligning bar down andsimultaneously disengage all the wheels 5 at the rst part of thedown-stroke of the key. When this movement is completed the member 72 ismoved to locking position to hold the free end of the aligningbaragainst turn movement. Before the down stroke of the key is completedthe universal bar returns to normal position allowing the carrier 34,under the force of its sprin 57, to move up to the position shown in ig.4. The e ect of this is to carry the right-hand end of the aligning barup with the carrier while the lefthand end thereof is held by thelocking member 72; the lookin bar at this time overcoming the force of te spring 43 and turning on the pivot 40. The locking bar is thus movedrelatively to its carrier 34 and is dis d in an oblique position, itsengaging edge assuming an angular position relative to the axis of thewheels 5, as shown-in Fig. 4. It is with the parts thus disposed thatthe right-hand end portion of the align ing bar successively engagesAvvheels 5 of the lower orders near the right-hand end of the series.The parts remain in this position until near the end of the returnmovement of the depressed key, when the associate l se-neck releases thedifferential shaft 68. As the latter returns to normal position thelocking member 7 2 will return to releasing position, thus freeing thealigning bar. When thus freed the spring 43 is eective to turn thealigning bar on its pivot 40 while the carrier 34 remains at rest. Theeffect of this ivotal movement of the aligning bar is to e evate oradvance the left-hand end thereof, thus bringing about a successiveengagement thereof with the remaining wheels 5 to the left; or as manyof them as it may be necessary for all practical purposes to engage. Ithas been pointed out that the lli master dog 30 coacts with the masterwheel so that in practice it is unnecessar to align the righthand orlower order whee 5 by the aligning ba'r 39. It is also unnecessary inpractice for the bar 39 to coact with one, or even several of the wheelsto the left of the alining bar. Therefore when I refer herein and in theaccompanying claims to the aligning bar engaging a series of Wheels, itwill be understood that the entire series of wheels 5 are notnecessarily included by such terms.

The teeterin movement, of the aligningr bar so as to a vance first oneend thereof and then the other into engagement with the wheels and thussuccessivel engage them, I regard as an important eature of myinvention, as is the control of the aligning bar by the universal baranddiiferential shaft for bringing about the successive and lIropei'lytimed operation of the aligning The operation of a totalizer mi ht beone in which carr in is done to al carrying wheels above t e owest, orone in which the totalizer is cleared by addin to aiegistered number thecomplement 0% that number. Probably trouble caused by the spiral inclearing operations is more annoying than that caused by it/in carryingoperations, since clearing operations are frequently performed, whereascarrying operations in which carrying is done to several wheels at atime are performed only occasionally or rarely; the spiral not occurringso as to be troublesome except when a number registered at thesight-openings contains a long succession of either nines or naughts.

yIt will be understood that the greater the number of register wheels,the greater the liability of spiraling, since the longer the series ofwheels the greater is the amount of lost motion in the carrying geartrain. In a totalizer'carrying a suiliciently long series of wheels,tlie spiral would absorb all of the motion derived from a carrying wheelof the lowest order, so that not any-of it would be imparted to thehighest carrying wheel. In the `present instancel I have shown fifteentotalizer wheels, a rather long series; and in practice the justifyinmechanism of my invention has proved e cient iii use with such a`totalizei.

It will be observed that the construction is such that the spring43 isrendered alternately eifective and ineil'ective to produce a, pivotalmovement of the aligning bar 39 around its pivot that the spring 43constitutes a connecting means by which the aligning bar is connected toits carrier 4t or moving means, and that the axis'of the pivot 40 iscontained in a lane at right-angles to tlie axis of the whee 5 and thecarrier 34 swings in such a plane so that the aligning bar swings on itspivot 40 in a plane at right-angles to the plane of movement of thecarrier 34 to eiiectv the described movements of the aligning bar.

Various changes may be made without departing from my invention.
